SPECIFICATION forming part of Letters Patent No. 755,214, dated March 22, 1904.

Application filed March 13; 1903.

To a/ZZ whom it mag/concern:

Be it known that I, URI H. BROWN, a citizen of the lUnited States, residing at Zanesville, in

vthe county of Muskingum and State of Ohio,

' side thereof; and its main object is toprovide new and improved means by which'the cultivator-beams may be swung laterally to'one side or the other by the foot of the driver, either simultaneously-both moving toward one side or the other together-orseparately, each being moved independently of the other in order to guide the cultivator-blades properly around any irregularities in the corn.

It .has for a further object the providing of a new and improved yoke by which the cultivator beams may be connected so as to swing laterally together, but which may be separated in such a way that either beam Amay swing laterally independently of the other and by the adjustment of which the distance between the cultivator-beams from side to side may be varied and set at different distances apart.

1n the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is a rear elevation. Fig. 3 is a top or plan view of the cultivatorbeams and the means by which they are laterally swung. Fig. 4 is an enlarged detail V- showing the mechanism employed when the view, partially in section, of the foot-lever and its pivot, showing its Amethod of support upon the cultivator-beam. Fig. 7 is an enlarged detail, being a section on line 7 7 of Fig. 2. Fig. 8 is an enlarged detail, being a `arched axle.

top view of the top portion of the `yoke con-` Iiecting the cultivator-beams; and Fig. 9 is an enlarged detail, being a rear view of the side parts of the yoke connecting the cultivatorbeams, showing the cultivator-beams in crosssection.

Referring to the drawings, l() indicates an 11 indicateswheels journaled upon the outer ends of the said arched axle.

12 indicates a seat-beam supported from the arched axle 10A and carrying a seat 13.

14 indicates the top frame of the cultivator carried'upon the axle 10, and upon which the usual hand-levers 15, rack-bars 16, and connecting devices are mounted. As these handlevers,'rackbars, and connecting devices for the lifting of the cultivator-beams may be of any well-known and approved form and description andl form no part of my present invention, it isbelieved that it is unnecessary to describe them more fully here.

17 indicates the front arch of the cultivator, which is carried upon the frame 14 and supports pipe-boxes 18 upon its outwardly-turned ends, which are of the usual form and construction and-form no part of my present invention.

19 indicates the tongue of the cultivator. 2O 2l indicate cultivator-beams, which are connected with the pipe-boxes 18 by means of the usual yokes 22 23. These yokesv are of the usual form and description and are constructed inthe Well-known way to permit the cultivator-beams to swing both vertically, so as to raise them from the ground, and laterally or from side to side.

24 25 indicate pivots, which, as best shown in Fig. 6, are conical in shape and are secured in an upright position upon suitable supports 26, fastened to the cultivator-beams 2O 21.

27 indicates foot-levers provided with stirrups 28 and having a long arm 29, ashort arm 30, and a bearing or socket 31. The bearing or socket 31 is bored centrally inga conical shape to it over and turn'upon the pivot 24. The pivot 24 and bearing or socket 31 are conical in shape in order to take up wear.

By making the pivots 24 25 conical in shape and of suitable height and" by providing the foot-levers 27 with sockets 31, bored centrally in a conical shape to fit over the pivots 24 25, the levers are also given a rm support, so that they may not only be used in swinging the cultivator-arms laterally, as hereinafter described, but also to force the cultivatorshovels into the ground when the levers are pressed by the foot of the operator.

32 indicates bolts, which arc screwed upon the top of the pivots 24 in order to secure the levers 27 in place. l

33 indicates links, the rear end of each of which is pivoted in the short arm 30 of the levers 27 and the other end pivotally connected with lugs 34, carried upon the outwardlyprojecting ends of the arch 17.

The lugs 34 are adjustably secured upon the outwardly-projecting ends of the arch 17 in such a way that they may be slid in and out thereon and secured in any desired position. By this means an adjustable connection is secured by means of which the cultivator-beams may be spread apart or brought somewhat more closely together and held in the desired position.

35 36 indicate bent levers, which are pivoted in lugs 37 38 upon each side of the frame 14. The lower ends of the levers 35 36 pass through bearings 39 40, mounted upon the outsides of the cultivator-beams 2O 21 and swiveled thereto, as best shown in Fig. 9. The bearings 39 4Q are so constructed that they may slide up and down upon the lower straight ends of the levers 35 36 as the cultivator-beams are raised or lowered.

Referring to Figs. 7 and 8, 4l 42 indicate bars which are pivotally connected, respectively, with the upper ends of the bent levers 35 36. 43 indicates a clip which is secured to the outer end of the bar 41 and embraces the bar 42. 44 indicates a clip which is secured to the outer end of the bar 42 and embraces the bar 41. The bars 41 42 near their central portions are slotted, as is shown in Fig. 7, and are secured at any desired adjustment, sliding upon one another in the clips by means of a bolt 45 and a wheel-nut46. It is obvious that when the wheel-nut 46 is loosened the cultivator-beams may be spread apart or brought together, rocking the levers 35 36 on their pivots either toward or away from each other at their lower ends and moving their upper ends correspondingly either away from or toward each other, the bars 41 42 slidingin the clips 43 44, whereby the distance between the cultivator-beams may be adjusted and when the desired adjustment is reached may be locked in position by screwing home the wheel-nut 46. When thus held together, it is obvious that either cultivator-beam or both may be raised or lowered, the bearings 39 40 sliding on the lower ends of the levers 35 36. It is also obvious that if either cultivator-beam is swung laterally the other one will be swung in the same direction. For instance, if cultivator-beam 20 is swung toward its adjacent wheel the lower end ofthe lever 35 will be swuno1 in the same direction, the upperend of the lever 35 will be swung inward, carrying the upper end of the lever 36 in the same direction and swinging the lower end toward the center of the machine, carrying with it cultivator-beam 21 and moving it in the same direction and the same distance as cultivator-beam 20. In other words, the beams will be swung in unison. This swinging is accomplished by means of the foot-levers above described.

In case it is desired by the driver to swing the beams to the right the lever 27, which is connected with the cultivator beam 21, is pushed forward by the foot of the driver resting in the stirrup 28. This, as is indicated by dotted lines in Fig. 3, will swing the cultivator-beam 2l to the right of the driver, and by the action of the levers 36 35 with the beams the other cultivator-beam 20 will be swungin the same direction into the position shown in dotted lines in Fig. 3, the foot-lever 27 connected with the beam 2l, being swung backward, as is shown by dotted lines in said figure. When it is desired to return the cultivator-beams to their original position, the foot-lever 27 connected with the beam 20 is pushed forward until the beams assume their original position. In case the cultivatorbeams are to be swung to the left of the driver the foot-lever 27 mounted upon the beam 2O is swung forward, when the reverse of the movements above described takes place. In case it is desired that the beams should not swing simultaneously, but that they should be laterally swung together, the wheel-nut 46 and bolt 45 are removed and the bars 41 42 allowed to either slide freely upon cach other or to slide out of their clips entirely and allowed to hang idle. In this case either beam can be moved outward toward the adjacent wheel by thrusting forward the foot-lever connected with said beam. In this case, however, the swinging of one beam will notswing the other, and consequently the pushing forward of the opposite foot-lever will not return the beams to their original position.

Referring to Fig. 4, 47 indicates aretractile springwhich is secured at one end to a suitable lug 48 on each of the cultivator-beams 20 21 and connected at its other end with the short arms 30 of the levers 27.. This spring, which is used only when the top portion of the connected yoke is disengaged, serves by its contraction to return the cultivator-beams to their original position after having been swung outwardly by the forward movement of the foot-lever.

IOO

While I have said that my improvements apply particularly to a riding-cultivator and have shown and described them in such a cultivator, it is obvious that the yoke by which the beams are connected could be used equally well with the walking-cultivator and that handles of the usual form could be attachedt'o the cultivator-beams for such purpose.

It will be seen that by constructing the separable yoke which connects the cultivatorbeams as above described-that is to say, by

aving its side levers pivoted to the cultivatorframe and the upper ends of said levers projecting above the frame-the cross-bars which connect the top of the yoke are sufliciently high above the frame to clear the corn, and at the same time an unobstructed view of the corn can be had by the driver sitting on the seat between the sides of the yoke and below the cross-bars as the machine is driven in the field. The cross-bars also by reason of their height form a convenientl rest for the lines.

That which I claim as my invention, and desire to secure by Letters Patent, is
